Chief Keef says back rent was not the trigger for his eviction … he tells us he was booted from his apartment because his neighbors just didn’t like him.

TMZ previously reported … Keef was evicted from his unit in Highland Park, Illinois Tuesday. Sheriff’s deputies escorted him out, and there were reports he owed $11,300 in back rent.

But our photog spotted a self-professed “turnt up” Keef in West Hollywood hours after the eviction … and he says it’s not about money … it’s because, “I’m too bad, I guess I’m a bad little young boy, I gotta go.”

Obviously unfazed, The Almighty Sosa posted a video where he was “looking for houses.” Take a look at both clips and just know if you’re in the neighboring area of Highland Park, Chief Keef may be coming to a community near YOU.
